The Schedule referred to in those Letters P atent and making part of thesame To all whom fit may concern Be it known that I CHRISTIAN PETERSON,of Red Wing, inlthe county-of Goodhue and State of Minnesota, haveinvented anew and valuable Improvement in Fanning-Mills and I do herebydeclare that the following is a full, clear, and exact ,description ofthe construction and operation fof the same, reference being had -to theannexed drawing making a part of this specification, and to the lettersand figures Figurel of the drawing is a top viewv of my fauning-mll.

Figure 2 is a side view of the same. y

. Figure 3is a vertical section, showing cylinder H.

Figures d and 5 are details.

My invention relates to means for cleaning grain from chaff, andconsist-s in the construction and novel arrangement of a perforatedcylinder aiiixed horizontally in a fanning-mill and made to revolve insuch manner that while it serves as a sievefor separatingv the grainfrom impurities, shall also serve as 'a conduit for the winnowed grain,to conduct it to the rear of such mill.

My fanning-mill is constructed in the usual form, and with the ordinaryapparatus, except that I add thereto the following devices, namely zUpon the main working shaft of the mill I attach a drum for a belt orcord, which said drum is marked a on the drawing.

The letter c represents a cord or belt operated byl this drum andextending forward to the drum or pulley a upon the shaft next mentioned.

Theletter d represents a rotating shaft arranged upon suitable bearingson the outer side of the front end of the mhh-and to which the drum u isattached, as shown.

At the end of this shaft @opposite the drum a, I

attach the beveled pinion s, which works and'meshes with the beveledpinion u, ,in the manner represented on fig. 3 of the drawing.

The letter H represents a `cylinder' constructed -in the form of a wheelwith cent-ral shaft c, vertical and,

longitudinal arms, the whole surrounded, except at the ends, withwire-cloth marked 7L on one end and fm at the other.

The wire-cloth h is constructed of finer wire and closer meshes than thecloth an, as shown on fig. 3.

Thisinclinatiou is designed to serve as means for under Atheconducting-tube l of the sieve-shaker,

which apron'serves to conduct thegrain into thel cylinder, while thechaff and other impurities pass away to the opposite side of the mill. t

The cylinder H is operated by means of the beveledpinionfa, upon the endof its shaft, as represented ong. 3.

Suitable boxes or drawers are placed under cylinder H, to receive thegrainthat passes through the meshes of its wirecloth covering.

It follows that the smallest kernels fall through the fine cloth 71.while larger kernels fall through the coarse cloth m, and the verylargest kernels remain in the cylinder, are conveyed to its front end,and passed off in the trough y. f

The foregoing constitutes the main portion of my improvement, but notall.

In the hopper of the mill I have arranged a gate, asshowu on Iig. l,intended to afford novel means for regulating the now of grain and chad`to the sieves.

It consists of a sliding plate, marked T, arranged in grooves on theside of the hopper, as shown, andv an apparatus for opening or closingthe aperture behind said plate at will. This apparatus consists of apo'st, r, that serves as a fulcrum for my lever, and is firmly attachedto the 'outside' of the hopper; also, of the lifting-block t firmlyunited to the plate T and the lever z, arranged as shown.

By means of this apparatus the plate T, which covers the only opening inthe bottom of the hopper, may be operated at will, and such openingclosed` or enlarged at the will of the operator.

I claim as my invention- `In a farming-mill, constructed as hereinshown,
